What a 3/5 rating means
On the comedogenic scale, a 3 is the moderate midpoint: tolerated by many, a possible trigger for congestion-prone skin. That puts Myristyl Alcohol squarely in the judgement-call zone, where your skin type and the product's formula decide the outcome.
This rating is disputed. Credible sources land on different numbers for Myristyl Alcohol, so we publish the range (3) rather than a false single figure. When sources disagree this openly, your own experience carries real weight.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Myristyl Alcohol near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Myristyl Alcohol
It is a fatty alcohol — a waxy, moisturising ingredient, not the drying kind of alcohol. A C14 fatty alcohol repeatedly listed as comedogenic in the moderate range.
On a label it can read as Myristyl Alcohol, Tetradecanol — worth knowing when you scan an ingredient deck.
Myristyl Alcohol in makeup and skincare
It thickens foundations, cream blushes, conditioners, and lotions. Its irritancy is rated separately at 0/5, which is low.
